The SW1500s feature numerous prototype specific details, traction tires, blacken metal-wheels, innovative drive train and truck design, directional-controlled LEDs and AZL’s AutoLatch™ couplers. As a bonus, AZL’s Innovation Lab is including two adapters that allow the SW1500 to be retrofitted with Micro-Trains™ 905 couplers. Note: We are advising customers not to attempt to remove the shells of the SW1500s. Doing so may result in damage to the locomotive’s shells.
